Problem 125c

Given information

Given that Approximately 86.5% of Americans commute to work by car, truck, or van. Out of that group, 84.6% drive alone and 15.4% drive in a carpool. Approximately 3.9% walk to work and approximately 5.3% take public transportation.

The main objective is to find how many would you expect to travel alone to work, if 1,000 workers are randomly selected.

From part 125(a), the table of the given situation is shown below:

Step-by-step explanation

The formula to find the probability of an event A is defined as .

Assume that the walkers walk alone, so, the percent of all commuters travel alone to work is .

Suppose that 1,000 workers are randomly selected.

Then the number of workers that would expect to travel alone to work is .
